- Loose connector at control board
How to fix it
- Unplug the range and inspect sensor wiring for breaks.
- Check connector at the control board for secure fit.
- Test sensor resistance with multimeter; infinite reading means replace sensor.
⚠ When to call a pro: If sensor tests open and replacing it does not fix, the control board may be faulty.
